Application filed May 3, 1912. Serial No. 694,923.

To all whom it may concern:

Be it known that we, JOSEPH H. CHAMP and THEODORE H. SCHUTT, citizens ofthe United States, and residents of Cleveland, county of Cuyahoga, andState of Ohio, have jointly invented a new and useful Improvement inLiquid-Dispensing Devices, of which the following is aspeclfication, theprinciple of the invention being herein explained and the best mode inwhich we have contemplated applying that principle, so as to distinguishit from other inventions.

The present improved apparatus, while generally adaptable to thedispensing of liquids, is more especially designed with regard to thedispensing of syrups and the like, as at soda fountains;

The object of the invention is to provide a simple and automaticallyoperable device that when the faucet handle isturned will discharge apredetermined, or measured, quantity of the syrup or other liquid.

A further object is to provide means for eliminating the dripping, whichis an annoying incident to the operation of such faucets as at presentconstructed.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims. v

The annexed drawings and the following description set forth in detailcertain mechanisms embodying the invention,

such disclosed means constituting, however, but several of the variousmechanlcal forms in Whigh the principle of the invention may be use Insaid annexed drawings :Figure 1 is a central vertical section of adevice or apparatus embodying our present improvements; Figs. 2, 3 and 4are transverse sectional views of such device taken on planes indicatedby the correspondingly numbered lines on Fig. 1; Fig. 5 is a viewcorresponding to Fig. 1, but showing a modification in the constructionof the device; Figs. 6 and Z are transverse sectional views of suchdejust described.

vice taken on planes indicated by the corre-v spondingly numbered-lineson Fig. 5.; Fig. 8 isa view similar to Fig. 1, but illustrating yetanother modification in the construction of the device; and Figs. 9, 10and 11 are transverse sectional views of such device taken on planesindicated by the correspondingly numbered lines on Fig. 8.

The syrup isdesigned to be supplied to the dispensing device, whichforms an object of present interest, under suitable pressure, and it isimmaterial whether this pressure is secured by gravity, that is, byhaving the supply tank at a relatively higher elevation than thedispensing apparatus, or whether it be secured by placing such tankunder' air or other gaseous pressure. The device itself, havingreference to the constructional form illustrated-in Figs. 1 to 4,inclusive,

comprises primarily a cylindrical chamber 1 having an inlet connection 2for the supply thereto of syrup from a source such as Chamber 1 ispreferably vertically disposed and within it is reciprocably held apiston 3 of such weight as to normally sink to the bottom of thechamber, or rather into contact with an adjustable stop 4: mounted insuch bottom, whereby the downward movement of the piston may beregulated. Provision is made, however, that under no circumstances shallthe piston entirely close connection across the bottom of the chamberbetween the inlet opening 2 previously referred to, and a second opening5 that is connected with a by-pass 6 leading to a valve casing 7 at apoint conveniently located above the piston chamber. Such valve casingis adapted to receive a valve plug 8 of familiar tapered form, operableby a handle 9, and constitutes the dispensing faucet. Valve plug 8 isprovided with a central passage 10 having apertures or ports 11 and 12,adapted in one position (that shown in Fig. 1) to aiford freecommunication the piston chamber 1 and the by-pass 6, thus equalizingthe pressure on both sides of the piston so that the latter will drop tothe between the upper portion of r bottom of the chamber by reason ofits weight. The portion of the chamber above such piston is thereupon,of course, filled with syrup which is admitted thereto through theby-pass. Other ports 13 and 14 in the valve plug serve, in a position ofthe latter angularly related to the position just described, to connectthe upper portion of the piston chamber 1 with the discharge opening ormouth 15 of the faucet, the connection with the by-pass 6 beingsimultaneously closed. In this last-described position of the valveplug, the pressure on the upper side of the piston is, of course,relieved so that the force of the syrup on the underside thereof raisessaid piston and causes the syrup in the upper portion of said chamber toflow from the valve and be discharged from the latters mouth. The casing7 is formed with an opening 24, and in the closed position of the valveplug communication is established between this opening and the dischargemouth 15 by a groove 23 formed in the valve plug. When the valve is inclosed position therefore, the discharge mouth is open to atmosphericpressure both from above and below, and consequently any syrup remainingin the discharge mouth will tend to run out instead of graduallydripping from the mouth.

The piston carries a stopper valve 16 on its upper face that is adaptedto tightly close the opening 17 in. the upper end of such chamber whenthe piston is raised, thus making it unnecessary that the piston betightly fitted in said chamber. Upon restoring the handle 9. of thevalve to its normal position, the pressure on the top and bottom of thepiston is again equalized and the upper portion of the piston chamberfilled with syrup, the quantity being determined by the location of thestop which limits, as before stated, the downward movement of thepiston.

In the modification of the construction illustrated in Fig. 5,substantially the same arrangement of piston and by-pass obtains as inthe case of the'first described form of the invention, and these partsare correspondingly designated. A more extended discharge tube ormouth-piece 18, however, is provided in connection with the valve thatcontrols the operation of the device, and in addition to the passage inthe valve plug and ports for variously connecting such passage,attention is directed to the lateral extension of the port 11controlling the upper by-pass connection. This lateral extension 19serves, as the valve plug is being restored to its normal position,toadniit a small quantity of syrup under pressure into the passage 10 intheplug, while the port 14 in the latter is still connected with thedischarge 15. This syrup under pressure causes the body of syrup alreadyin the discharge tube .Figs. 8 to 11 inclusive, where again the generalarrangement and operation of the parts is the same as in the firstdescribed construction, with the addition of a special discharge tube ormouth piece 18. The valve casing 7, however, is provided with anadditional connection 20 whereby air maybe brought thereto, and inproper position of the plug 8 be admitted into the discharge opening 15through grooves 21 and 22 forming passages in the bearing surface of theplug, as shown in Figs. 8 and 9. The disposition of these latterpassages is such that the air is admitted in small quantity incidentallyto the restoring of the valve to its normal position, the effect beingto force out the residual syrup collecting in the discharge tube of thedevice so that dripping is prevented. It is, of course also undesirablethat this syrup should be allowed to collect in said tube, as it willdry and tend to clog up the same.

Other modes of a plying the principle of our invention may e employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.
